Hello, Flora. My name is Jessica. I'm calling because I was watching with my kids the secrets of life of pets.

And we lived in New York City and we were wondering how many animals have they found in this subway or the sewer lines.

Thank you. Bye.

Hi, Flora. Hi, Jessica. How are you? I'm well. How are you? Good, good.

Are you on the subway a lot? Daily, um, yes. It's my commute from where to where? From the Bronx to Manhattan.

How long? Oof. Our 15? Each way.

Who's he? You spend a lot of time on the trains. I do. That's why we had the question because we're always taking us away everywhere.

And also because my kids watch the secret life of pets and there you can see this fluffy bunny living on the ground together with a bunch of piranhas and tarantulas.

Welcome to the Underbelly Brothers Home Flash Tests.

So we were wondering, even my kid was asking me, ask Flora, if there's any stray dogs and cats and cobras hiding, lurking under New York. I said, okay, I'll ask her.

What animals are they interested in? My little one, he's seven years old and he's interested in all kind of animals.

I took him to the zoo one day and there was this big road. You know the ones that look Madagascar Roaches, I think they are.

Oh, yeah. His thing roaches, right? Exactly. They're super big and he wanted to haul this so badly and he said his favorite animals are rats. So you take it from there.

Jessica, your son is going to love this story.

You asked what animals live in the subways and sewers and we have just the person to answer your question.

My name is Jason Munchy South. I'm a biology professor at Fordham University. Jason studies urban dwellers, the animals that live in New York City.

There's all sorts of cool animals that are making their way back into the city. Foxes, raccoons, skunks, possums. They've been the odd river otter here and there.

Really? Jason has also spent a lot of time studying the animals below ground. He spent months going deep into the subway system to figure out what lives there.

Brave.

And first things first, Jason said you shouldn't imagine the cast of a universal pictures cartoon riding the rails.

No, any animal larger than a rat that is living down there, it's probably temporary and would have been brought by somebody and let go.
